One object of my invention is to provide a longitudinally movablecarrier having a driving motor mounted thereon with its shaft verticallydisposed and extending above the 1 carrier, together with means on thecarrier for supporting the end of the shaft, thereby tending toeliminate any undue vibration of the shaft so as to effect a smoothlyrunning driving belt.

Another object is to provide a means fixed on the carrier and arrangedto extend over the driving pulley in position to engage the extremeupper end of the motor shaft to resist the strain or tension of thespindle driving belt on the shaft bearings of the'motor.

Another object is to provide a combined support for the free end of themotor shaft and a horizontally disposed shielding element for thedriving pulley.

Another object is to provide certain improvements in the form,construction and arrangement of the parts whereby the above named andother objects may effectively be attained.

A practical embodiment of my invention is represented in theaccompanying drawings, in which Fig. 1 represents a detail sideelevation of one end of a spinning and twisting machine, a portion ofthe auxiliary frame being broken away to more clearly illustrate theapplication of my improved means thereto.

Fig. 2 represents a plan view of the same, and

Fig. 3 represents a vertical section, on a larger scale, taken intheplane of the line IIIIII of Fig. 2, looking in the direction of thearrows.

In the drawings I have illustrated my invention as applied to ,aspinning and twisting machine, of which only one end frame has beenshown, it being obvious that a similar end frame is provided forsupporting the end of the several bars, etc., upon which are mounted theguide pulleys and spindles interposed between the end frames. The endframe is denoted by 1, the pairs of rods 2, 3 disposed on opposite sidesof the frame 1, upon which rods are mounted the bearings 4, 5 of theguide pulleys 6, 7 respectively, and the bearings 8, 9 of the spindles10, 11 respectively.

An upright 12 is spaced from the frame 1 and connected thereto byhorizontally arranged rails 13, 14. A carrier 15 is disposed between therails 13, 14 and arranged to move lengthwise towardand away from the endframe 1 and upright 12. The carrier comprises a horizontally arrangedplate 16 provided with anti-friction rollers 17, 18 at one end and asimilar pair of rollers 19, 20 at the other end. The rails 13,14 areformed with inwardly extending upper flanges 21 and lower flanges 22,between which flanges the antifriction rollers are arranged to travel toconvey the carrier 15 horizontally thereon.

A motor 23 is suspended from the plate 16 of the carrier 15 by means ofbolts 24. The upper end bearing 25 of the motor extends upwardly throughan opening 26 in the carrier' and the motor shaft 27 which pro'ectsvertically from the end bearing 25 has xed thereon a driving pulley 28arranged to receive an endless driving belt 29. This belt is disposed topass through openings in the end frame, around guide pulleys 6, 7,then-lengthwise through the machine in position to contact with thespindle whirls30 and around guide and idler pulleys at the other end ofthe frame (not shown), the construction and arrangement of which iswell-known in the art.

In order to maintain the driving belt at a constant tension, the carrier15 is provided with a rack 31 arranged to be engaged by a pinion '32fast on one end of a shaft 33 journaled in a bracket 34, which issecured to the upper flange 21 of the rail 14. The other end of theshaft 33 has a pulley 35 adjustably fixed thereon in position to receivea strap 36, one end of which is secured to the pulley 35, while theother end is provided with a. weight 37 which depends therefrom.

From the foregoing it will be seen that a constant tension will beapplied to the belt 29 by the weight 37 tending to rotate the pulleythrough the strap 36, which pulley moves the shaft 33 and pinion 32which, in. turn, transmit their rotary motion to the rack 31 on thecarrier 15, thereby moving Lhe carrier with its motor and driving pulleyoutwardly towardthe upright 12, automaticall tightening the belt andmaintaining a uniormtension on the belt at all times.

It has been found in practice that, where the shaft of the motor ismounted vertically and extended upwardly to support a horizontallyarranged driving pulley, a maximum strain is exerted on the free end ofthe shaft, which strain in time tends to bend the shaft and place itsoutof balance, thereby causing an uneven movement of the driving belt andparts associated therewith. Furthermore, the tension of the belt andpulley on the free end of the motor shaft causes the motor shaftbearings to wear unevenly, whereupon the shaft, when in motlon, vibratesin the bearings and creates undue noise.

In order to overcome the above named and other disadvantages, I providethe carrler 15 with a bracket 38 having a horizontally disposed footpiece 39 and a vertically arranged lug 40. The foot piece 39 of thebracket 38 is secured to the plate 16 of the carrier by means of bolts41 and nuts 42, which coact with slots 43 in the foot piece and slots 44in the plate 16. The slots with the bolts provide a lateral adjustmentof the bracket on the plate 16. An angular adjustment of the bracket iscompensated for by means of a depending ridge 45 on the foot piece 39,which rests on the plate 16 to form a pivot, and

screws 46 threaded to move vertically in the foot piece 39 and havingtheir lower ends adapted toengage the plate 16. Thus, by

' the movement ofthe screws 46 in the foot piece and their engagementwith the plate, the bracket may be rocked on the ridge 45.

An arm 47 is arranged to overhang the pulley 28 and extend downwardlybetween 4 the driving belt 29, the lower end of which arm is secured tothe uprising lug 40 of the bracket 38 by means of bolts 48 and nuts 49.The arm 47 is also provided with slots 50 which coact with bolts 48 foradjustment purposes. The upper and outer end of the arm 47 is providedwith a bearing 51, in which is journaled the upper end of the motorshaft 27. By this arrangement the motor shaft 27 is supported at itsouter end and the tension of the belt on the pulley equalized betweenthe bearing 51 and the motor shaft bearin 25. Furthermore, the shaft ismaintained in proper balance and any vibration transmitted in motion isreduced to a minimum.

A horizontall disposed shield52 is formed inte al with tiie arm 47 andextends outwar y from the bearing 51 so as to overhang the pulley andserve as a guard for the pulley and belt. It will, therefore, be seenthat, since the arm 47 is disposed on the carrier 15 between the belt 29and with the shield 52 arranged to overhang the pulley 28, the belt mayreadily be removed and replaced on the pulley without displacing the armand shield.

It is evident that various changes ma be resorted to in the form,construction an arrangement of the several parts without departing fromthe spirit and scope of my invention; and hence, I do not intend to belimited to the details herein shown and described, except as they may beincluded in the claims.
